Our group of four adults took the half day Spencer Glacier/Placier River float trip and thoroughly enjoyed it! The staff were all so friendly, knowledgeable, helpful and accommodating - we missed the Portage Train Station (it doesn't say Portage Train Station anywhere on the sign FYI), and were running late, and the staff held up the train waiting for us even though it made them have to really hustle to keep everything else on time. We soooo appreciate that! They gave us boots to put on and we enjoyed the short train ride. Once you arrive, you board a bus which takes you down to the Glacier lake and you have plenty of time to take photos. They assign you to a raft and a guide - we had 8 of us plus the guide in our raft. They go over all of the safety rules and then you are off! Our guide was fantastic and shared so much of his knowledge of the glacier and the area with us. We were able to paddle right up to the icebergs as we floated among the many there. After a bit we took off down the river and enjoyed a smooth river float taking in all of the scenery and learning about the area from our guide. They also passed out some hot chocolate and cookies along the way. It was a wonderful way to see the area, float among some icebergs and enjoy being outside. If you are in the area and looking for something to do, I would definitely recommend them.
